CHALK-CUP.

To all whom it may concern:

Be it known that I, CLARENCE R. BROWN, a citizen of the United States, and a resident of Creighton, in the county of Knox and State of Nebraska, have invented a new and useful Chalk-Cup, of which the following is a specification.

My invention relates to billiard cue chalk holders and its principal object is to provide a chalk holder which will permit a new chalk element to be insertedtherein after the old one has been worn, and which will retain such chalk element against theft.

Further, the invention provides a chalk holder wherein one wall is pivotally mount- 7 ed and is normally held against movement to lock the chalk element against extraction by the usual flexible element for suspending the holder.

The invention also contemplates a chalk cup or holder which will prevent theft of chalk and which is of comparatively simple construction and can be manufactured at a nominal cost. 1

With the preceding and other objects and advantages in mind, the invention consists in the novel combination of elements, constructions and arrangement of parts, and operations to be hereinafter enlarged upon, defined in the subjoined claims and illustrated in the accompanying drawing, wherein:

Figure 1 is a side elevation of a chalk cup constructed in accordance with my invention;

Fig. 2 is a vertical sectional view of the same, showing the device in locked position; and

Fig. 3 is a similar view showing the device in unlocked position and the chalk element partly extracted therefrom. 7

Referring in detail to the drawing wherein like characters of reference designate corresponding parts, the numeral 5 designates a substantially rectangular cup open at one end and at one of its vertical sides. The upper wall 6 is concave.

The cup 5 is provided with a pair of laterally disposed ears 7 at the upper end of the open side and mounted in these cars 7 is a pin 8. A wall or door 9 is disposed at the open side of the cup and is provided with laterally disposed ears 10 at its opposite longitudinal edges at the upper end thereof, which are also pivotally mounted on the pin 8.

Specification of Letters Patent.

Patented Mar. 15,1921.

Application filed June 16, 1920.. Serial No. 389,422.

A'coil spring 11 encircles the pin 8 and has one end extended laterally to engage one set of the adjacent ears 7 and 10 while i the opposite end of the coil spring is positioned against the outer face of the door or wall 9 and normally retains the same parallel to the sides of the cup, as illustrated in Fig. 2. The hinged end of the door or wall 9 is formed with an inwardly directed lateral extension 12 which is concave and normally lies within the concave wall 6; The extension 12, as is clearly shown in Figs. 2 and 3, overliesthe chalk element and upon rocking the hinged wall 9 to the position shown in Fig. 3, the part 12. will engage the chalk element and eject the same from the cup.

The wall 6 and lateral extension 12 are provided with coinciding openings 13 through which a suspension or flexible ele ment 14 is extended to afford a loop which terminatesina knot 15 that is arranged exteriorly of the cup 5. Normally this loop is drawn taut and tied; asshown in'Fig. 2

with a new one, the flexible element is untied to permit slack in the same and thus allow the door or wall to be swung to the angular position, illustrated in Fig. 3.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the in vention or the scope of the subjoined claims.

Having thus described my invention, what I claim as new and desire to secure and protect by Letters Patent of the United States, is:

1. A chalk holder including a tubular body open at one side, a wall hinged to the open side, a laterally and inwardly disposed extension carried by the pivoted end of the wall and overlying the chalk element received in the body and adapted to engage the former to eject the same upon swinging the hinged wall to one side, and a suspension element passing through one end of the tuto hold the wall against pivotal movement bular body and the extension and normally drawn taut to hold the wall against pivotal,

movement and adapted to be slackened to permit the wall to be swung to one side for the extraction or insertion of an element in the body. a y y 2. A chalk holder including a hollow body open at one side, a pair of ears disposed at the open side of the body, a wall normally overlying the open side of the body and provided with ears, a pin passing through all of said earsand upon which the ears carried by the wall are adapted for pivotal movement, and a loop passing through the body and wall and normally drawn taut and adapted to be slackened to permit the wall to be disposed at an angle for the insertion or removal ol a chalk element from the body.

3. A chalk holder including" a hollowbody open at one side, a pair of laterally disposed ears formed at the open side of the body, a wall normally overlying the open side of the body, lateral ears carried by the wall, a pin passing transversely through the ears and upon which the last mentioned ears are adapted for pivotal movement, a laterally and inwardly disposed extension carried by the wall, and a flexible loop passing through the body and extension and normally drawn taut to retain the wall against pivotal movement and. adapted to be slackened to allow the wall to be disposed at an angle for the insertion or extraction of an element to and from the body.

a. In a device of the character described,

a substantially rectangular hollow body' open at one end and at one side, a wall disposed at' the open side of the body, a pin extending transversely at'the open side of the body and pivotally supporting the wall, a coil spring encircling the pin and normally holding the wall pivotally to the sides of the body, and a loop passing through the closed end of the body and the wall and normally drawn taut to hold the wall against pivotal movement, and adapted to be slackenedto permit the wall to be disposed at an angle for the removal or insertion of a cube in the body, the free end of the pivoted wall and the lower ends of the body being bent inwardly to hold the cube in the body.

5L- A chalk holder comprising a chalk holding body open at one side, a chalk element received in the body, a wall pivoted at the open side of the body, an inwardly directed extension carried by the wall and overlying the chalk element, and means for V normally holding the wall against pivotal movement and adapted to be released whereby to permit the wall to be swung to one side to engage the extension with the chalk element to eject the same from the holder.
